Can anyone recommend a conformal coating that can be applied manually (dispensed or brushed) that isn't so volatile the operator needs special equipment/ventilation? A fast cure time/method would be helpful also. thanks John

I believe Humiseal (and others) makes some water based coatings...www.humiseal.com Dymax has a no VOC UV cure if you have an adequate UV source.

Humiseal has no-VOC coatings Acrylic and Urethane on offer, they too have non-VOC silicones and new UV curable also...!!!

In our house we have had some of our BGA's reballed because it was a lead-free part and wanted to place on a leaded assembly. Hope this helps.

The concern about lead contamination of lead-free solder has to with zone refining. For more, look here: http://www.smtnet.com/forums/Index.cfm?CFApp=1&Message_ID=30315

That's pretty funny.............change the cognex card. Jim you indeed have an interlock problem an if this is a UP-3000 which I suspect it is there are several interlocks if I recall correctly.

Jim, You need to repair or by-pass the cover interlock. The machine thinks it's open and will not procede any further. They all do it, even the new models. Once you get past this warning - you will get the the RESET window - garanteed.
